A Go implementation of the Uxn virtual machine, by nf.

• Full support for Varvara's System, Console, Screen, Controller, Mouse, File, and Datetime devices.
• Live-reloading and rebuilding of uxntal source (-dev).
• An interactive debugger (-debug).
• Runs on macOS, Linux, and Windows (mostly tested/developed on macOS).

• Implement the Audio device.

• The File device is not well-tested, and likely has bugs.
• The button events of the Mouse device somehow misfire.
• Included source files are not watched by the -dev feature.
• The GUI doesn't always shut down when exiting the debugger.
